Description

Convenient electric hair drier

The application requires the priority of Chinese patent application with the application number of "201910546817.1" and the invention name of "convenient electric blower" filed 24/6/2019 and Chinese patent application with the application number of "201910739004.4" and the invention name of "convenient electric blower" filed 12/8/2019.

Technical Field

The present invention relates to an electric hair dryer, which is particularly suitable for drying hair.

Background

At present, most of hair dryers for drying hair on the market need to be held by hands for drying operation, which is very inconvenient and easy to cause fatigue in various occasions such as drying long hair.

CN104783472A discloses a strong magnetic attraction type automatic head shaking air blower. CN203087949U discloses a rotary hair dryer. CN208581919U discloses a hair dryer support with swing function. CN104621944A discloses a suction cup type safety hair dryer. Although the blower device can realize the adjustment of hand-free operation, the blowing direction and the like by providing the separated or integrated modified bracket, the blower device has the problems of complex structure, inconvenient use and carrying, and particularly, the problem that the convenient switching between the hand-held operation mode and the hand-free operation mode can not be realized at any time and any place.

Disclosure of Invention

The invention aims to provide an electric hair drier which can conveniently realize the switching of a handheld-hands-free operation mode.

According to the present invention there is provided an electric hair dryer comprising a hair dryer body and a retaining member or mechanism connected thereto, wherein the retaining member is configured to reversibly snap-convert between a handle and a support by self-shape change. The quick switching concept enables the switching of the hand-held-hands-free operation mode of the electric hair dryer to be conveniently realized.

In the present invention, "the shape change of the holding member itself" means the change in the shape of the holding member itself, and does not include such a case: the retaining member does not substantially change in structural configuration but merely changes in position relative to the blower body, such as changes in the pivot position.

According to a particular embodiment of the invention, the retaining member has a connecting end for connecting the hair dryer body and another opposite free end (non-connecting end). The free end of the retaining member is configured to be quickly scale-up modifiable to increase its bearing surface when used as a stand. The retaining member may be quickly switched or converted from an initial handle to a fixed bracket by enlarging and modifying its free end, thereby easily converting to hands-free blowing operation.

According to one embodiment of the invention, the retaining member may comprise at least one (preferably 2-4, e.g. three) wing around its free end, which serves as a handle when not flared and as a support when flared (umbrella open). The holding member has a simple structure, and can realize the switching or conversion of the blowing mode very conveniently.

Although other variants are also possible, such as a quick-connection (e.g. plug-in) of a fastening or fastening plate at the free end of the holding element, or even an outward ejection or pulling of an expandable supporting plate or supporting rib from the free end, the use of such "umbrella-opening" variants or variants of the invention is clearly more advantageous in terms of structural integration and ease of use. Further, in such "open umbrella" embodiments of the invention, the distal ends (expandable ends) of the tabs may be disposed at the free end of the retaining member and may be expandable outwardly therefrom by 0-90 ° ("positive open" mode); or the proximal end of the tab (the attached end) may be disposed at the free end of the retaining member and the distal end of the tab may flare or flip 90-180 deg. outward toward the free end of the retaining member (the "reverse" mode). Compared with a reverse opening mode structure, the forward opening mode structure is simpler and more convenient to operate; the "kick-back" mode configuration may allow the retention member length to be extended or increased (within approximately the length of the airfoil) to allow for adjustment of the blow height.

In addition, it is also possible to integrally form the blower body with a hollow handle, and store the holding member of the present invention in a withdrawable or ejectable manner therein. By housing the holding member in the hollow handle, the holding member can be converted into the handle; the change of the handle into the fixed bracket is achieved by pulling the holding member out of the hollow handle and expanding and modifying the free end thereof.

According to a further preferred embodiment of the invention, the distal ends of the wings may also be substantially in the same support plane as the free ends of the holding member when flared for use as a stent. This construction makes the support more robust.

In addition, the free end of the holding member may be provided with a suction cup or a friction pad. The distal ends of the fins may also be provided with friction pads, respectively. Such a structure may further enhance the support stability.

According to a further preferred embodiment of the invention, the holding member is telescopic in its longitudinal direction, for example by configuring the holding member as a telescopic or multi-stage antenna type structure. The structure can realize convenient adjustment of the blowing height. The telescopic sleeve can be designed to be capable of adjusting the telescopic length and staying and fixing at any length position; alternatively, the stepped positioning sleeve may be designed so that it can stay fixed at different length setting positions.

According to the electric hair dryer of the present invention, the holding member is preferably movably attached to the hair dryer body. The movable connection mode is convenient for adjusting the blowing angle and the blowing direction. Herein, the blower body is a holding member, and includes a casing, various components in the casing, various accessories arranged on the casing and not in motion, and the like.

The movable connection can be either a separable connection or an inseparable connection.

According to one embodiment of the inseparable articulation, the retaining member may be pivotally connected to the blower body by a hinge. The pivotal connection allows the retaining member not only to be conveniently adjusted in blowing angle when used as a stand, but also to be folded relative to the hair dryer body to facilitate carrying or storage of the retaining member in a suitable position on the hair dryer body. The hinge can adopt a hinge capable of arbitrarily positioning a pivot angle, so that the hinge can be arbitrarily pivoted and stays fixed at the current pivot position; alternatively, a stepped positioning hinge may be used that allows it to be pivoted and positioned at different set angles.

The hinge may further be fixed to a rotatable shaft provided on the holding member. The structure can give consideration to the adjustment of the blowing angle and the blowing direction. The rotatable shaft can be rotated and stopped to be fixed at any current position; or may be fixed in different orientations in stages.

According to one embodiment of the detachable articulation, the retention member may be attached to the blower body by a magnetic adapter. In this case, the adapter is preferably constituted by an iron ball provided on one of the blower body and the holding member, and a receptacle containing a ring-shaped magnet provided on the other of the blower body and the holding member to magnetically receive the iron ball therein. The movable connection mode has a simpler structure, can adjust the blowing angle and the blowing direction under the condition that the holding component is used as a bracket, and is very convenient for the quick separation of the holding component and the hair drier body, so that the hair drier is more convenient to carry and store.

Of course, the magnetic matching device is not limited to the specific combination structure of the iron ball and the ring magnet, and any suitable magnetic matching connection mode is possible: for example, a ferromagnetic member and a magnet or a magnet and a magnet.

According to another embodiment of the inseparable articulation, the retaining member may also be connected to the blower body by a freely deformable cord (flexible cord). The structure can also realize multiple adjustment of the blowing angle, the blowing direction and the blowing height.

According to yet another embodiment of the inseparable articulation, the retaining member may be attached to the blower body by a friction ball mechanism. The friction ball mechanism may include a receptacle, a rotary ball and a friction pad, the rotary ball being tightly fitted and inseparably received in the receptacle through the friction pad surrounding the rotary ball (to be rotatable in any direction under an external force against a frictional force and to stay at a current position when the external force is removed). In this case, the receptacle may be provided on one of the blower body and the holding member, and the friction ball may be connected to the other of the blower body and the holding member by a link.

In the case of a retention member movably attached to the blower body, the retention member may be retractable with respect to the blower body to enable the entire electric blower to have a single continuous cylindrical shape, such as a cylinder, an elliptical cylinder, a spindle cylinder, or a rectangular cylinder, when not in use.

In the case where the retaining member is inseparably movably connected to the blower body, at least a portion of the blower body may have a defective barrel cross-section, the cross-section of the retaining member being complementary in shape to the barrel cross-section of said at least a portion of the blower body to form a substantially complete barrel cross-section when the retaining member is fully retracted relative to the blower body (collapsed to an initial minimum volume state).

Further, the hair dryer body may include a front barrel working part for performing a blowing operation function and having an air inlet formed at a rear end thereof, and a rear barrel receiving part formed with an air inlet cavity for receiving therein a power cord for supplying power to the front barrel working part, the air inlet cavity communicating with the air inlet of the front barrel working part, the front barrel working part having a full barrel section, the rear barrel receiving part having a defective barrel section with respect to the front barrel working part, and when the holding member is completely retracted and retracted with respect to the rear barrel receiving part, a section of the holding member is complementary to a barrel section of the rear barrel receiving part to form a substantially full barrel section in conformity with the front barrel working part.

In the case where the holding member is detachably movably attached to the hair dryer body, the hair dryer body may include a front barrel working section and a rear barrel receiving section which are arranged in line, the front barrel working section being for performing a blowing operation function and a rear end of the front barrel working section being formed with an air inlet, the rear barrel receiving section being formed with an air inlet cavity for receiving therein a power cord for supplying electric power to the front barrel working section, the air inlet cavity being communicated with the air inlet of the front barrel working section, the front barrel working section and the rear barrel receiving section having a substantially continuous uniform barrel sectional shape, and the rear barrel receiving section being further for receiving therein the separated holding member. In addition, the rear barrel housing part may be detachably or detachably connected to the front barrel working part, so that the electric hair dryer becomes lighter and more lightweight when in use by removing the rear barrel housing part.

The single barrel configuration makes the hair dryer of the present invention very compact and attractive when not in use, such as when stored, minimizing space usage and eliminating the messy cord.

Further, the electric hair dryer of the present invention may further comprise a cover for covering at least a rear end of the rear barrel housing portion when the power cord or the holding member is received in the cavity of the rear barrel housing portion.

According to a preferred embodiment of the present invention, the holding member may be attached to a side surface of the blower body. The side connection or lateral connection mode can enable the holding component to be connected to the left and the right of the center of gravity of the hair dryer body, so that the operation and the use are convenient. Of course, the attachment position of the holding member may be provided at other positions, for example, in the vicinity of the other end of the blower body longitudinally opposite to the air outlet.

As other variations, the free end of the retaining member may also be provided with a magnet or be designed as a clip to facilitate flexible fixed use of the hair dryer in different situations.

According to the electric hair dryer of the invention, the holding member can be conveniently switched to be used as a handle of a hand-held mode and to be used as a bracket of a hand-free mode, so that the electric hair dryer is more flexible and convenient to use. In addition, the retaining component also adopts a simple structure to realize the quick and flexible adjustment of the blowing angle, direction and height.

Detailed Description

The present invention is described in detail below with reference to the attached drawings. It should be understood by those skilled in the art that the following illustrative embodiments are only for purposes of explanation and not limitation of the invention.

Figures 1-3 show an electric hair dryer according to a first embodiment of the invention, generally comprising a dryer body 10 and a holding member 20 connected thereto. The hair dryer body 10 is provided with a switch 11, an external power cord 12, an air outlet 13, an air inlet 14, a heating element, a motor (not specifically shown), and the like.

Fig. 1 is a schematic view showing a hand-held state of the electric hair dryer of the first embodiment, in which the holding member 20 is folded or collapsed into a rod shape for a holding operation by hand.

Fig. 2 is a schematic view showing a hands-free state of the electric hair dryer of the first embodiment, in which the holding member 20 is unfolded or expanded to be fixed to a stand for a hands-free blowing operation on a floor.

Fig. 3 is a schematic view showing a hands-free state of the electric hair dryer of the first embodiment, in which the holding member 20 is unfolded or expanded as a fixed bracket as shown in fig. 2 and is elongated in its longitudinal direction to raise the blowing position.

As shown in fig. 1-3, the holding member 20 is pivotally connected to the side of the blower body 10 in a vertical plane (shown in the drawing sheet) by a hinge 21. The hinge 21 may be a hinge that can arbitrarily position the pivot angle, so that it can be arbitrarily pivoted manually and stays fixed at the current pivot position; alternatively, a stepped positioning hinge can be used that can be manually pivoted and positioned at different set angles. The retaining member 20 comprises a shaft 22, a hinge seat 23 at the upper end (connecting end) of the shaft and three expandable wings 24 at the lower part of the shaft. The distal end of the flap 24 forms a support foot shape and the proximal end is connected to the shaft 22. When the tabs 24 are open, their distal ends may also be substantially flush with the lower end of the shaft 22 in the same plane to facilitate firm support on a suitable table. For stable support on the table top, the distal end of the flap 24 may also be provided with a friction pad 240 and the lower end of the shaft 22 may also be provided with a suction cup or friction pad 220, as shown in fig. 2 and 3. By means of the above-mentioned pivotal connection, the blowing angle (the angle between the blowing direction and the shaft 22) can be adjusted very conveniently. In addition, the hinge mount 23 is rotatably mounted with respect to the shaft 22 to facilitate adjustment of the blowing direction. The rotation of the hinge base 23 relative to the shaft 22 can be performed manually and stay fixed in any current orientation; or may be fixed in different orientations in stages.

In the "open umbrella" embodiment shown in fig. 1-3, the distal or openable ends of the tabs 24 are disposed at the free end of the retaining member 20 (lower end of shaft 22) and are expandable outwardly therefrom by 0-90 ° ("positive open" mode). However, it is also possible to position the proximal or attached ends of the tabs 24 at the free end of the retaining member 20 such that the distal ends of the tabs 24 flare or flip 90-180 ° outward toward the free end of the retaining member 20 ("reverse open" mode). Compared with a reverse opening mode structure, the forward opening mode structure is simpler and more convenient to operate; the "kick-back" mode configuration may allow the retention member to be extended or increased in length (within approximately the length of the wings) so that adjustment of the blow height can still be conveniently achieved without the provision of the retractable sleeve described below.

As best shown in fig. 3, the shaft portion of the shaft 22 is formed of a multi-stage (e.g., two to five stages) retractable sleeve 25 to facilitate extension or shortening of the shaft 22 to adjust the blow height. The telescopic tube 25 can be designed to be capable of manually adjusting the telescopic length thereof and staying and fixing at any length position; alternatively, the stepped positioning sleeve may be designed so that it can stay fixed at a set length position.

Figures 4-6 illustrate an electric hair dryer in accordance with a second embodiment of the present invention generally similar to the embodiment of figures 1-3, wherein the retaining member of figure 4 is shown in cross-section and like numerals indicate like parts; the difference lies in that: the retaining member 20 in this embodiment is attached to the blower body by a magnetic adapter instead of the rotatable hinge mount structure of the first embodiment. As shown more clearly in fig. 4, the magnetic counter comprises a receptacle 16 provided on the hair dryer body 10 and an iron ball 26 provided at the upper end of the holding member 20, the receptacle 16 having a ring magnet 17 disposed therein. The holding member 20 is arbitrarily rotatably and quickly detachably attached to the hair dryer body 10 by the attracting engagement of the iron ball 26 with the magnet 17 in the receptacle 16.

Figures 7-8 show an electric hair dryer according to a third embodiment of the invention, which has a different configuration from the second embodiment described above, except for the different manner of articulation of the retaining member 20 to the hair dryer body 10. Figure 7 shows the holding member 20 extended with respect to the body 10 of the hair dryer, and it can be seen that the holding member 20 is attached to the body 10 of the hair dryer by means of a friction ball mechanism. Further, as shown in fig. 8, in the retracted state, the blower body 10 is formed integrally with the holding member 20 in a continuous cylindrical shape.

As shown more clearly in fig. 9, the rubbing ball mechanism includes a receptacle 16a provided on the blower body 10 and a metal rotating ball 26a provided on the upper end of the holding member 20. The rotating ball 26a and the holding member 20 may be connected together by a screw structure. A friction pad 17a is also provided in the receptacle 16 a. By the tight fit of the rotating ball 26a with the friction pad 17a in the receptacle 16a, the holding member 20 can rotate in any direction under an external force against the friction force and stay in the current position when the external force is removed. The receptacle 16a and the rotating ball 26a are sized such that the rotating ball 26a can only rotate in the receptacle 16a and cannot disengage from the receptacle 16 a.

The hair dryer body 10 shown in fig. 8 includes a front barrel working part 101 and a rear barrel receiving part 102 which are arranged in a line, the front barrel working part 101 for performing a blowing operation function and a rear end of the front barrel working part 101 being formed with an air inlet (not shown), the rear barrel receiving part being formed with an air inlet cavity 103 for receiving therein a power cord 12 for supplying power to the front barrel working part 101, the air inlet cavity being communicated with the air inlet of the front barrel working part 101, the front barrel working part 101 having a full barrel section, the rear barrel receiving part 102 having a defective barrel section (fan face) with respect to the front barrel working part 101, and when the holding member 20 is fully retracted and retracted with respect to the rear barrel receiving part 102, a section of the holding member 20 is complementary in shape to a barrel section of the rear barrel receiving part 102 to form a full barrel section (circular section) in conformity with the front barrel working part 101.

Fig. 8 also shows the cover 18, and the cover 18 is used to cover the rear end of the rear-barrel housing portion 102 after the power cord 12 is received in the cavity 103 of the rear-barrel housing portion 102. Of course, the cover 18 may also be designed to completely cover the rear end of the electric hair dryer.

Figures 10-12 show an electric hair dryer in accordance with a fourth embodiment of the present invention, in which the connection between the retaining member 20 and the hair dryer body 10 is a detachable connection, using the magnetic adapter connection of the second embodiment shown in figures 4-6; in addition, the whole electric hair dryer is a complete cylinder, and the holding member 20 can be received in the cavity 103 of the hair dryer body 10 like a power cord after being separated from the hair dryer body 10 and covered by the cover 18 (fig. 11 and 12).

Fig. 13 shows an electric hair dryer according to a fifth embodiment of the present invention, which is similar in structure to the fourth embodiment described above, except that the front barrel working part 101 and the rear barrel housing part 102 are not integrally formed but are connected together by a detachable or detachable connection means such as a screw or a snap. The advantages of this structure are: the rear barrel receiving portion 102 can be removed to make the electric hair dryer lighter in use.

Fig. 14 shows an electric hair dryer according to a sixth embodiment of the present invention, which is similar in structure to the third and fourth embodiments described above, except that the rear barrel housing portion 102 is eliminated (thereby making the whole electric hair dryer appear shorter) while allowing the holding member 20 to be turned forward relative to the hair dryer body 10 toward the air outlet 13 to form a single continuous cylindrical shape of the whole electric hair dryer.

It will be appreciated by those skilled in the art that the features of the various embodiments described above may also be combined with one another, for example, the electric blowers of the first and second embodiments may also take the form of a single barrel configuration of the third, fourth, fifth or sixth embodiment.
